> 3 dayInstalled 4 into my rig, 3 in and 1 out. Much quieter than the box fan I was using to cool my PC(lol). Came with a nice supply of Y cables, extension, etc. Would purchase again if I needed more.

> 3 dayAls ich in meinem PC einen neuen CPU-Kühler (NOCTUA NH-U9S plus NOCTUA NF-A9 PWM) einbaute, habe ich auch diesen Lüfter mit Low Noise Adapter eingebaut. Er sitzt vorne im Gehäuse und zieht die Luft in den PC rein und bläst sie dann an den Festplatten entlang. Alle Sensoren zeigen niedrige Werte, die Drehzahl bleibt insgesamt niedrig und zu hören ist er fast gar nicht. Alle erforderlichen Montageteile und eine sehr gute bebilderte Montageanleitung liegen bei. Insgesamt sehr empfehlenswert.

> 3 dayThis is the king of quiet PC fans. I checked specs on a number of them, and none match this for both noise levels and airflow.

> 3 dayFantastic fan. Whisper quiet under normal conditions and hardly noticeable even when spinning at full. Beautiful packaging, extras included are great. Even at low speeds it pulled far more far than the stock fan that came with my case. Definitely worth the extra money to buy them.

> 3 dayDrei verbaute Lüfter halten mein Gehäuse (1x) und meine CPU AMD Ryzen 7 1700X (2x) unter Last (CPU 4100Mhz / RAM 3200MhZ) bei einer CPU Temperatur von 69° und Gehäuse bei 45°. Die Lüfter sind nicht lautlos aber für mein Empfinden sehr leise.

The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
SSO2 bearingThe NF-S12A features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Scope of delivery
|
Anti-Stall Knobs
The NF-S12A"s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan"s stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.
